Absolute and relative morbidity burdens attributable to various illnesses and injuries among active component members of the U.S. Armed Forces, 2025.

This annual summary quantifies the impacts of various illnesses and injuries among members of the active component of the U.S. Armed Forces, using a disease classification system and morbidity burden measures derived from the Global Burden of Disease Study. In 2025, the burden of health care for U.S. service members in the active component was determined by medical diagnostic categories within a limited range: Injuries, mental health disorders, and musculoskeletal diseases accounted for the vast majority of health care provided. This concentration was most evident in ambulatory, or outpatient, care, to which only 5 specific conditions constituted one-third of all outpatient medical encounters. Inpatient treatment for mental health-related disorders comprised 51.0% of all hospital bed days for active component service member health care.
